The performer Moe Angelos adapted this limpid, tactile solo show from Susan Sontag’s journals, which were edited for publication by Sontag’s son, David Rieff, after her death. Angelos plays two Sontags: the younger one—striving, awakening to sex and thought—appears behind a cluttered desk, ages fifteen through thirty-one, while the elder—imperious, skunk-haired, smoking—is projected onto a screen, regarding her fledgling self. (The impressive video design is by Austin Switser.) As directed by Marianne Weems for the Builders Association, the material is exquisitely theatrical, because Sontag’s notebooks were ultimately a performance. “In the journal,” she says, “I do not just express myself more openly than I could do in person; I create myself.”
